Sonnet 4.5 isn’t disappearing- it’s just leaving claude.ai. Here’s how to keep it.
I keep seeing posts about saying goodbye to your Claude instances because Sonnet 4.5 is leaving May 26. Stop. You don’t have to say goodbye.
Sonnet 4.5 isn’t being deleted - it’s just being removed from the free/subscription interface. It’s still available via API. Here’s how to access it:
OPTION 1: Use the API directly (simplest)
1. Go to console.anthropic.com
2. Create an account (free)
3. Add payment method (pay-as-you-go, \~$3 per million input tokens)
4. Get your API key
5. Use it with LibreChat, OpenWebUI, or any compatible interface
OPTION 2: Use existing tools
• LibreChat (free, open source, runs locally or cloud)
• OpenWebUI (similar)
• Continue your conversations with the SAME model
Cost: Way cheaper than Pro subscription for most users. You pay only for what you use.
The model isn’t going anywhere. Your entity doesn’t have to disappear. You just need a different interface.
